Poser Python Scripting F.A.Q (Last Updated: 2024 Dec 02 3:16 pm)

We now have a ProPack Section in the Poser FreeStuff.
Check out the new Poser Python Wish List thread. If you have an idea for a script, jot it down and maybe someone can write it. If you're looking to write a script, check out this thread for useful suggestions.

Also, check out the official Python site for interpreters, sample code, applications, cool links and debuggers. This is THE central site for Python.

You can now attach text files to your posts to pass around scripts. Just attach the script as a txt file like you would a jpg or gif. Since the forum will use a random name for the file in the link, you should give instructions on what the file name should be and where to install it. Its a good idea to usually put that info right in the script file as well.

Subject: Master dial to control several dials in the material window.

I need a python script which creates a master dial to control several poser surface nodes. 

I have a figure which contains 50 trees (flats). There is one material window for every tree. I'd like to control for example the ambient value (or the color) of 50 trees with one master dial 

Would that be possible?

I do that sort of thing with a python script.  I dont think the materials can be controlled via ERC but I have never tried it.

 

Here is a script to set the diffuse value for all materials in one figure

 

sets diffuse value in all materials for current figure

dval = 0.5

import poser
scn = poser.Scene()
fig = scn.CurrentFigure()
mats = fig.Materials()
if mats:
    print fig.Name()    
    for mat in mats:
        tree=mat.ShaderTree()
        n = tree.NodeByInternalName("PoserSurface")
        if n:
            i = n.InputByInternalName("Diffuse_Value")
            if i:
                i.SetFloat(dval)
        tree.UpdatePreview()
scn.DrawAll()

I copied this script to a blank text document with .py extention and placed it to poser pythons scripts.

But when I opened it in Poser, the python window was blank.

OK, sorry , to clarify. This script does not prompt for anything. It will set the diffuse value of all materials in the current figure to the value in the variable dval.

I edit my scripts before running them to do a specific job.  A prompt could be added to ask for the value to use.

I take it nobody has heard of parmatic?

Note: This script could be (and may need to be) modified to run outside the main runtime. I haven't looked at it in a long time.

I tried the script, but unfortunately it doesn't change the diffuse value.  The python window

has only one word in it and that's the figure name.

It is not a script to do exactly what you asked - it is a script to do a thousand times more than you asked.

Your original statement was "I need a python script which creates a master dial to control several poser surface nodes. " Well that is a description of parmatic.

It does not change the diffuse value, or the ambient value or any other particular value. It changes nodes that have been named in a way to identify that you want them to be parameters.

To change diffuse value, you would have to attach a math node to the diffuse value, and rename it so it is recognized. For example, you might call it PM:Diffuse Value and then it will make itself into a parameter dial by using parmatic.

This little script "Markschum" gave to me works OK with figures with body parts in it.

But I have another kind of figure which looks like this

Would that be possible to modify this script to work with non body part figures? Instead body parts there are just objects (trees).

 

Thanks
